The Korean launch vehicle Nuri will stand on the launch pad in the assembly building on the 20th. Attention is focused on whether the sky door can be opened on the 21st, overcoming twists and turns such as strong winds and parts abnormalities.
According to the Ministry of Science and ICT and the Korea Aerospace Research Institute on the 19th, the Nuri-ho, which has been repaired, will be transferred from the launch vehicle assembly building of the Goheung Naro Space Center in Jeollanam-do to the launch site from 7:20 am on the 20th for the second launch. The next day, the 21st, the goal is to launch at 4 PM.
This time, it is expected that the launch will be successful through all kinds of variables.
The Nuri was originally scheduled to launch a second launch on the 15th. However, on the 14th, one day before the launch, the weather conditions deteriorated due to precipitation and strong winds, so it was postponed for a day.
The launch plan was put on hold when an abnormality was detected in the first stage oxidizer tank level sensor signal during the process of standing and fixing on the launch pad on the 15th for the launch on the 16th.
However, the anti-accidental researchers succeeded in repairing the oxidizer tank level sensor that caused the problem by showing their wits and replacing them with new parts without separating the first and second stages.
Based on this, the launch management committee has set the 21st as the launch date. The launch preparation time schedule remains the same.
One of the key variables for the future is the weather. The rainy season is especially from the end of June to July. The preliminary launch date is until the 23rd. Even if the launch on the 21st fails due to bad weather, there is still two days left.
“The launch schedule may change depending on weather conditions in the future,” said Kwon Hyun-joon, director of large public research policy at the Ministry of Science and Technology, at a briefing on the 17th.
Meanwhile, the Nuri-ho is the first Korean projectile developed with pure Korean technology. If the launch is successful, it will become the 7th space power in the world to have launch vehicle technology that can send practical satellites of 1 ton or more into space.
